ldbl-128ibm-compat: Create libm-alias-float128.h
Add a new libm-alias-float128.h in order to provide the __*ieee128 aliases for the existing *f128 that do not have a globally exported symbol. * sysdeps/ieee754/ldbl-128ibm-compat/Versions: New file. * sysdeps/ieee754/ldbl-128ibm-compat/libm-alias-float128.h: New file.
